While the plate 24 is provided, a step e is formed inside the water discharge port 27 of the metal rectifier body 26 screwed to the water discharge port 23 via the sealing material 25, and this step e and the flow rectification on the cap side are formed. A plurality of mesh members (one mesh member 28 which is called a border net in the illustrated conventional example) is provided between the plate 24 and the plate 24.
And two net-like members 29, 29) called a caulking net. In addition, reference numeral 30 in FIG. 3 is a split pin for fixing to the current plate 24.

[0003]

The above-mentioned conventional water outlet rectifier has almost no swirling flow with splashing, has little turbidity due to suction of air bubbles, and has a generally good rectifying action. However, the rectification state was unstable and varied, and splattering and twisting sometimes occurred under the rectification state although the swirling flow did not occur. Alternatively, if there is a variation in the inner diameter of the water passage portion in the rectifier, turbulence tends to occur.

[0004] The present invention has been made in view of such circumstances, and has as its object to provide a rectifier for a water faucet spout in which the rectifying action is stabilized and improved.

[0005]

According to the present invention, means for solving the above-mentioned problems are constituted as follows. That is, according to the first aspect of the present invention, the first straightening plate is provided inside the water outlet of the synthetic resin cap attached to the tip of the water discharge pipe of the water faucet for supplying the water or the temperature-controlled mixed water. At the same time, a second rectifying plate sandwiched between the first net and the second net is provided in the rectifier main body made of synthetic resin, and the rectifier main body is screwed to the water discharge port in a watertight state. It is characterized by becoming.

[0006] Turbulent water (or hot water) flowing from the water discharge pipe toward the water discharge port is first primarily rectified by the first rectifying plate, and the turbulent flow component which causes the generation of swirling flow and droplets is effective. Is rectified. Next, the water flow is buffered by the first mesh body, so that the turbulent components are further reduced and the water flow is made uniform. Thereafter, secondary rectification is performed by the second rectifying plate, and rectification is almost achieved.
By being buffered by the mesh, the remaining turbulent components are reduced and removed, and the flow is made uniform, so that a stable rectification without swirling flow or splash can be obtained. In short, in the present invention, rectification can be more stably obtained by performing rectification and buffering in two stages.

According to a second aspect of the present invention, in the water faucet rectifier of the first aspect, a space between the first rectifying plate and the first mesh and between the second rectifying plate and the second mesh. It is characterized in that a predetermined gap is set between them.

[0008] By providing a gap between each straightening plate and the mesh body, the flow rate of water is reduced and the pressure is reduced in the gap, thereby further improving the buffering effect.

According to a third aspect of the present invention, there is provided a water faucet rectifier according to the first or second aspect, wherein the first net, the second rectifying plate, the second net and the rectifier main body are connected to each other. It is characterized in that the inner diameters of the water parts are all set to the same size.

Since the water passages are formed linearly by making the inside diameters of the water passage portions below the first mesh body all the same, the rectification is further promoted.

According to a fourth aspect of the present invention, the first rectifying plate according to any one of the first to third aspects is characterized in that ribs are radially arranged.

The radially arranged ribs can effectively reduce the swirling flow energy.

According to a fifth aspect of the present invention, the second rectifying plate according to any one of the first to fourth aspects is a combination of radially arranged ribs and concentrically arranged ring bodies. It is characterized by:

[0014] By combining the ring with the radial ribs, a finer rectifying action can be obtained.
